turns out/ends up

I introduced Richard to Mike, but it turns out that they went to college together.

 

Hi,

Does "turns out" in the above amount to "ends up?" Thanks.

Does "turns out" in the above amount to "ends up?"

One 'amounts to' the other in the sense that both are associated with the idea of final results or conclusions, but the grammar and more detailed meaning of the two expressions is different, so you can't make an exact subsitution.

It turns out that they ..., but They ended up ---ing.   Not It ends up that they ..., nor They turn out ---ing.

It turns out that they went to college together. = The facts that were revealed in the course of the conversation were such that we ultimately realized that they had gone to college together. 

They ended up going to college together.  =  As the result of the course of events and/or decisions leading up to their actions, they went to college together. = The final result was that they went to college together.
